Drag each statement below to its correct category as true of

Drag each statement below to its correct category as true of either prokaryotes or eukaryotes to review differences in gene expression.

Solution

Answer:

Prokaryotes

Eukaryotes

1. No nucleus, so transcription and translation can occur concurrently.

2. Genes are not divided into introns and exons.

3. The initiator RNA carries formylmethionin.

4. The small ribosomal subunit immediately binds to the ribosome binding site (AUG).

5. Primary transcripts are mRNAs with a triphosphate at the 5’end.

6. mRNAs have multlple ribosome binding sites.

7. Single RNA polymerase.

1. Nucleus is separated from cytoplasm by nuclear membrane. So transcription takes place in thr nucleus, but translation in the cytoplasm.

2. Genes consist of introns and exons. Introns must be removed and exons spliced after transcription.

3. The initiator RNA carries methionin.

4. The small ribosomal subunit binds to the 5’ cap and then scans the mRNA to locate the ribosome binding site(AUG).

5. Primary transcripts undergo processing to become mature mRNA(As with 5’ cap and poly-A tail).

6. mRNAs have only one start site.

7. Several kinds of complex RNA polymerases.
